Cutting edge design, expert craftsmanship, top quality metals and advanced manufacturing processes come together in unparalleled luxury and style. T-REX Upper Class Series Grilles feature embedded fine woven formed mesh positioned within the precision laser cut frames. All Upper Class Series Grilles are available in polished stainless steel or black finishes. We use several different materials throughout the design process. Our grilles are manufactured using mild steel, stainless steel and aluminum. Our stainless steel is high quality 304 alloy which we use for all our polished frames, wire mesh and mounting brackets. Other components such as cosmetic trims are manufactured from 5052 Aluminum and 304 Stainless Steel depending on the application. Our uncompromising quality begins with advanced 3D CAD supported engineering and design. All our products undergo rigorous testing for fit, finish, drivability and durability. Each part starts with a custom jig using laser cut materials, precision TIG welding and meticulous assembly and quality control. This dedication of American craftsmanship shows in every product that leaves our facility in California.
